Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Nose and Nasal Cavity

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Summary

This report details a rare sinonasal fibrosarcoma case in a 47-year-old woman. Surgical removal was successful, confirming the diagnosis through histopathology.

Area of Science:

Oncology
Otorhinolaryngology
Pathology

Background:

Sinonasal fibrosarcoma is a rare malignant neoplasm.
Clinical presentation often includes nasal obstruction and epistaxis.
Diagnosis relies on histopathologic and immunohistochemical analysis.

Observation:

A 47-year-old woman presented with a 2-year history of left nasal obstruction and proptosis, plus 2 months of diplopia.
Imaging revealed a large neoplasm involving the nasal cavity, ethmoid and frontal sinuses, with extensive bone erosion.
The tumor eroded the maxillary sinus, lamina papyracea, cribriform plate, and frontal sinus wall.

Findings:

Complete tumor resection was achieved via endoscopic and Lynch incision approaches.
Histopathologic examination confirmed the diagnosis of sinonasal fibrosarcoma.

Implications:

This case highlights the importance of considering rare malignancies in sinonasal presentations.
Successful surgical management of extensive sinonasal fibrosarcoma is demonstrated.
Further research into sinonasal fibrosarcoma is warranted for improved diagnostic and therapeutic strategies.
